A. Introduction

1. Purpose of the Addendum to (EAR). This Addendum to the Environmental Assessment Report (EAR) was prepared based on a Chinese version of the Feasibility Study Report (FSR) and Environmental Assessment Table which was approved by Huanggang EPB in 2018 for the new proposed subprojects under Hubei Huanggang Urban Environment Improvement Project (the Project). The Addendum is to be submitted to ADB for review and approval.

2. The project. The Project is the first key urban environmental initiative of the Huanggang Municipality Government (HMG) with nationwide demonstration potential. The project design incorporates lessons from (i) Yi’ai Lake rehabilitation–a recent locally funded initiative, and (ii) other ADB supported lake and river restoration projects in the PRC. The project design was optimized based on best international practices: (i) the need to take an integrated approach to water system rehabilitation, and (ii) the importance of using simulation techniques to predict likely outcomes. The project will also complement the past and ongoing projects which are contributing to reducing pollution in the Yangtze River. Since the drinking water intakes of several cities are downstream from the Yangtze River, the project also contributes to protection of vital drinking water source.

3. Changes have been made to the project scope during the project implementation. During the ADB Inception Mission in November 2015, the PMO proposed the change of sediment dredging method from cutter suction dredging to drain and pump and the sediment treatment method from dewatering and solidification to vacuum pre-compaction. The PMO submitted the Due Diligence Report for Environment of Chiye Lake subcomponent in July 2016. During the ADB Review Mission in August 2016, other 8 changes were proposed by PMO according to the designs. The first Addendum to the EAR was prepared and submitted to ADB in June 2017 and revised according to ADB’s comments. In March 2018, PMO proposed another six changes for the midterm adjustment. Study Report (FSR) and the domestic Environmental Assessment Table completed have been completed in 2018. Please see chapter B for the detailed information of the changes.

4. Environmental Assessment for the Project. An Environmental Assessment Report (EAR) was prepared in accordance with the requirements of the Asian Development Bank (ADB) Safeguard Policy Statement (SPS 2009) on the basis of the domestic EIA report that meets the requirements of the People’s Republic of China (PRC) EIA Law (2003) and associated regulations. The EAR was prepared based on two domestic Environmental Impact Reports (EIR) prepared for this project: a planning EIR, and a construction project EIR; and supplemented with information from the domestic Feasibility Study Report (FSR) and the Soil Erosion Prevention Plan (SEPP) for the project.

5. This project is classified as Category A for environment on the basis of ADB’s Rapid Environmental Assessment (REA), requiring the submission of a comprehensive environmental impact assessment (EIA) report.

6. Bases of the second Addendum to the CIEE preparation. This Addendum is prepared primarily based on the information collected from the FSR, Environmental Assessment Table prepared for the new proposed Subprojects. The Addendum was prepared in accordance with both PRC environmental laws/regulations and ADB’s environmental policies. The Addendum preparation also followed both PRC and ADB guidelines on environmental assessment.

8. A comprehensive analysis of the feasibilities of the six engineering subprojects has been undertaken. The technical designs are suitable for local circumstances, topography, and climate (arid desert conditions with long, harsh winters), consistent with strategic and sector priorities, and PRC design guidelines and local regulations. For the more detailed information of the subproject technical designs and analysis, please see report of Technical Feasibility and Sector Analysis of Subprojects which would be submitted to ADB in 2018.

B1. Diversion Canal and Culvert Gate of Nanhu Pumping Station

1. Location 9. The location of the subproject is shown in Figure A-1.

Figure A-1 Location of Diversion Canal and Culvert Gate of Nanhu Pumping Station

2. Construction Content

4

10. Construction of inlet channel and sluice gates at the Nanhu pumping station. The works include the inlet channel to the Nanhu pumping station, and 5 sluice gates, which are Dongchang Gate, Dongtai Gate, Sanjiu Gate, Wuqi Channel Gate and Kuikou Lake Gate, respectively. The Nanhu pumping station intake channel is 305m long and 24m wide with a designed flow capacity of 30m3/s.

11. According to the Classification of Water Conservancy and Hydropower Projects and Flood Standards (SL252-2017), the slopes on both sides of the newly proposed inlet channel of Nanhu pumping station are graded as Class IV. According to the Article 3.2.3 of the Design Specification of Embankment Projects (GB 50286- 2013), the newly to-be-built earth dyke at Kuikou Lake of Nanhu Pumping is graded as Class IV. Designed discharge flow for the channel’s affiliated sluice gates is 30m3/s, classified as engineering Class III.

B2. Wuqi Channel

1. Location 12. The location of the subproject is shown in Figure A-2.

Figure A-2 Location of Wuqi Channel

2. Construction Content 13. Wuqi channel is a drainage and irrigation branch channel of Changhe River with a water area of 10.2km2, and the channel’s length is 4.6km. The average longitudinal gradient of the channel’s reaches is 1/19,000, the width of the river channel is 14~20m, the average width is 18m, and the depth is about 2m. The scope of Wuqi Channel’s rehabilitation is from the inlet of Nanhu pumping station to Sanjiu sluice gate at the entrance of Changhe River, and the total channel length is 1.1km, Works mainly include slope protection of river banks, river dredging, dyke top, greening and culvert reinforcement. The main sensitive point on the east side is 5

Huanggang Vocational Technical Institute, the residential houses on the west side of the channel are being demolished, and the land around the west side is mostly idle

14. Plane layout: considering that pipelines and plant measures have been laid on the side slopes of Wuqi Channel under this ecological restoration project, no major changes will be made to bank lines on both sides in the plane, and the layout measures will follow the original ones.

15. Vertical layout: dredging was conducted at the section of the channel for rehabilitation this time under the ecological restoration project, and aeration and water purification facilities were installed. Its river section and longitudinal slope can meet the water flowing requirements, but the height of the embankment on both sides cannot meet the flood control requirements. Therefore, with the longitudinal layout, the longitudinal section at the bottom of the original channel is not adjusted so as to maintain the existing slope ratio of 1/19,000. The embankment top on both sides is the same as the elevation of the water inlet’s embankment top determined by Nanhu pumping station that is 20.10m for the elevation of the embankment top at both sides.

16. In the light of on-site condition, storm-water pipelines will be built in the long- run and distributed and discharged into the planned water system in the community with pipe diameters of d600-d1000 and an average burial depth of 2m. In the short- run, a new d800-d1500 storm water pipe will be built within the south wall of the community and discharged into Wuqi Channel. In addition, wewage pipes are laid from west to east with pipe diameters of d300~d400, collecting sewage generated in the community, discharging into the sewage main trunks built under Wuqi channel interception project, and finally entering into the sewage system of Nanhu Industrial Park in the north through the lifting pump station.

B3. Sugong River and the East Extension of Qingshui River

1. Location 17. The location of Sugong River is shown in Figure A-3.

Figure A-3 Location of Sugong River

2. Construction Content

18. 7 rivers and channels were newly built under the existing project, namely, Linglong bay, Jinshui River, Qingshui River, Canglang River, Dongtai River, Dongchang River and Chushui River. Newly proposed ones are 2 channels of Sugong River and eastern extension of Qingshui River. Engineering design scope of eastern extension of Qingshui River ranges from Dongchang Avenue to Jiangbei Class I Road with a design length of 750m and canal bottom width of 14.2-56m; design scope of Sugong River ranges from the eastern extension of Qingshui River to Chushui River, design length 1680m, canal bottom width 16-187m. Dredging is proposed to be carried out at the eastern extension of Qingshui River with a dredging amount of 66,139m3; dredging is proposed to be carried out at Sugong River with a dredging amount of 319,550m3.

19. According to the key water system results of Baitan Lake surrounding area under Hubei Huanggang NED Baitan Lake Area Water System Improvement Planning Report, the maximum water over-flow of Sugong River and Qingshui River are 25.5m3/s and 5.6m3/s, respectively. Based on the key water system results of Baitan Lake surrounding area under Hubei Huanggang NED Baitan Lake Area Water System Improvement Planning Report, and the normal running water level of river channels in the construction drawings for Chushui River, Dongchang River, Dongtai River and Qingshui River, channels’ longitudinal slopes and canal bottom elevation are calculated and determined. The design canal bottom elevation of the eastern extension of Qingshui River is 14.85-14.91m with a water drop of 0.007692%. The design canal bottom elevation of Sugong River is 14.89-15.02m with a water drop of 0.007692% 7

20. The open ditch’s depth of Qingshui River’s eastern extension is about 4.7- 5.0m, mainly excavated slopes. The surrounding environment is open, and the current topography is mostly water pools with green land around, it needs to be formed cutting slope from top to bottom. The open ditch’s slopes are graded as Class III. The lateral soil is mainly silt, and silty clay mixed with silt. C20 precast hexagonal block is used to protect the normal water level on the downhill side. The open ditch of Sugong River has a depth of about 4.7-5.0m, mainly with low filling and shallow excavation slopes. The surrounding environment is open, and the current topography is mostly water pools with green land around. The open ditch’s slopes are graded as Class III. The lateral soil is mainly silt and silty clay.

B4. The Connection of Dongchang River and Dongtai River

1. Location 21. The works are located at the intersection of Dongchang River and Dongtai River with Nanhu Road. The location of the subproject is shown in Figure A-4.

Figure A-4 Location of the Connection of Dongchang River and Dongtai River subproject

2. Construction Content 22. Works on getting through the joints of Dongchang River and Dongtai River are located at the intersection of Dongchang River and Dongtai River with Nanhu Road. Existing box culverts at the intersection of Dongchang River and Dongtai River with Nanhu Road will be dismantled. One new box culvert of 2-BH=2-5.8m×3.7m will be built at the intersection of Dongchang River with Nanhu Road at a length of

8

55m; one new box culvert of 2-BH=2-5.8×3.7m will be built at the intersection of Dongtai River with Nanhu Road at a length of 69m.

23. According to Hubei Huanggang NED Baitan Lake Area Water System Improvement Planning Report, it’s planned that Nanhu pumping station Q=30m3/s would be newly built at Changsun dyke, directly draw flood water from Baitan Lake and discharge it into Bahe River. Based on the calculation of unsteady flow, the highest water level and flow rate for one lake and ten rivers are obtained with a designed once every 20 years. In the light of key water system results table for surrounding area of Baitan Lake under Hubei Huanggang NED Baitan Lake Area Water System Improvement Planning Report, Baitan Lake and Santan River meet the flood control standard of every 20 years for the surrounding area of Baitan Lake in NED; the design profile of the river and lake connecting channels, including Dongchang River and Dongtai River, can satisfy the demands for water passage and drainage of the connectivity, as well as the flood control and drainage for the planned Baitan lake surrounding area.

24. According to the plan, the design profile at the intersection of Dongchang River and Dongtai River with Nanhu Road should meet the requirements of water passage and drainage for the connection of rivers and lakes, taking a design flow of 30m3/s. The canal bottom elevation of Dongchang River is 14.753m, the highest water level is 17.862m, and the maximum water depth is 3.10m. The canal bottom elevation of Dongtai River is 14.815m, the highest water level is 17.925m, and the maximum water depth is 3.11m. The designed effective depth of the box culvert is 3.2m with 0.5m ultra-high.

B5. Chiyehu Road

1. Location 25. The location of Chiyehu Road is shown in Figure A-5.

9

Figure A-5 Location of Chiyehu Road

2. Construction Content 26. Chiyehu Road (the section from Chibi Avenue to Hubin Avenue) is a non- motorized lane, and positioned to be a slow-moving channel in the park. The road standard and positioning are the same as the lake’s ring road. The total design length of the road is 2,125.82m, the width of a standard profile is 8m, and the landscape green belt on the west side is 4m. Two new footbridges across Chushui River will be built. Starting from Hubin Avenue, along the road, it will cross Fanzhou Road and Chibi Avenue Within the project scope, there are 3 flat curves, with a minimum radius of 150m and a maximum radius of 900m. The road is positioned as a slow-moving road in the park. According to the standards of urban branch roads, no ultra-high and wide is set up.

27. According to the requirements of planning to control the maximum water level of 17.90m and the site elevation of land not lower than 18.8m, the vertical elevation of road should be kept no less than 18.8m. Combined with surrounding undulating terrain, the road longitudinal slope is controlled between 0.3% and 0.5% to avoid large filling and excavation. Horizontal slopes of the design road are 1.5%. According to the Regulatory Plan of Huanggang NED Baitan Lake Area, there is no relevant pipeline planning within the design scope of the road, therefore, no storm-water pipelines are arranged this time.

28. Construction sites of the bridges are all located in the cross-river area, where the ground foundation is relatively weak. It is advisable to give priority to the bridge scheme with light structure, while the construction should avoid the impact of flood during the flood season to the bridge site, and bridge structures with convenient and rapid construction should be adopted.

C. Description of Environment

29. Geographical location. Huanggang Municipality is located in eastern Hubei Province, south of the Dabie Mountain, bordering the northern shore of the middle reaches of the Yangtze River. It is approximately 170 km wide from east to west, and 200 km long from north to south. It borders Anhui Province to the east, the cities of Wuhan and Xiaogan to the west, and Henan Province to the north.

30. The Huangzhou District is located in southwestern Huanggang Municipality, on the northern shore of the mid-section of the Yangtze River, at longitude 114o50’∼115o05’ E and latitude 30o5’∼30o29’ N. It is surrounded by the Yangtze River to the west and south, the Ba River to the East, and mountains to the north. It has an administrative area of 353 km2, expanding 21.5 km from east to west, and 26 km from north to south.

31. The New East District (NED), within which the 25.26 km2 Baitan Lake planning area constitutes the development area, is located in the eastern Huangzhou District, and is east of the existing urban center in Huangzhou District.

32. Geology and topography. The topography of Huanggang Municipality shows gentle sloping in terraces from highlands in the north to lowlands in the south. There are high mountains in the north-eastern part of the Municipality, hilly ridges in the central part, and plains and lakes in the southern part. The Dabie Mountain range (highest altitude 1,729 m) in the north-east forms the watersheds for the Yangtze River and Huai River systems. Approximately 34.5% (5,964.6 ha) of the Municipality is mountainous. The hilly ridges in the central area are mostly below 300 m in elevation. In the south are elongated lake plains (altitude 10∼20 m) with crisscrossing rivers and lakes as well as scattering water ponds and branching streams. Elevation in the Baitan Lake planning area ranges from 9.3 m to 33.8 m, with an arithmetic mean of 19.8 m.

33. Soil types in the Huanggang Municipality include yellow-brown soil, red soil, alluvial soil and rice paddy soil. Yellow-brown soil is the dominant soil type covering an area of approximately 600,000 ha, which accounts for approximately 55% of the total land area. Yellow-brown soil is mainly found in the mountainous areas of Macheng, Luotian and Yingshan, providing essential forest soil. Red soil covers an area of approximately 173,000 ha, which accounts for 16% of the total land area. Red soil has a low pH of 4.5∼6.0 and is mostly found in the hilly central regions and transitional areas. Alluvial soil covers an area of approximately 40,000 ha, which accounts for 3.7% of the total land area and is mainly distributed along the alluvial plains of the Yangtze River and its tributaries in the area, providing fertile soil for dry cultivated land. Rice paddy soil covers an area of approximately 262,000 ha, which accounts for 24% of the total land area and is mainly distributed in the hilly and lake plains providing essential agricultural soil.

34. Seismicity. Huanggang Municipality’s tectonic structure is located in the border area of the Yangtze plate’s Dongbai-Dabie uplift and the lower Yangtze fault zone. Major fractures in the area belong to the interfaces of tectonic units, new tectonic units and its secondary structure, with complex structure and signs of multi- phase activity. Strong earthquake activity in the area is closely related to the faults. Presently the area is in an earthquake activity quiet period and there has been no comparatively strong earthquake activity in recent years.

11

35. According to the China Seismic Ground Motion Parameters Zoning Map (GB 18306-2001), the seismic intensity in the region of the project area is Grade VI. The PRC classifies seismic intensity into 12 classes under the China Seismic Intensity Table (GB/T 17742-2008), from Class I to Class XII based on the severity of “shaking” of the earth surface and the extent of potential impact. Class VI is intermediate in severity with most people unable to stand still and furniture falling.

36. Climate. Huanggang Municipality has sub-tropical continental seasonal monsoon climate with distinct seasons. Table III.1 summarizes Huanggang’s climate characteristics. Rainy days (≥0.1 mm) occur mostly during the spring and summer seasons and especially from mid-June to mid-July that could account up to 30% of the total annual precipitation. Persistent high temperature and scarce precipitation would generally occur after mid-July due to the influence of the Pacific subtropical high pressure, resulting in summer and autumn droughts.

Table C-1: Huanggang’s climate characteristics Annual average temperature 15.7∼17.1 oC Highest temperature (usually in July) 38.1 oC Lowest temperature (usually in January) -5.3 oC Annual average relative humidity 77% Annual average sunshine 1959.4 hr Annual frost free period 237∼278 days Annual average precipitation 1223∼1493 mm Total annual precipitation 22.237 billion m3 Highest one-day precipitation 224.7 mm Precipitation days (≥ 0.1 mm) 115∼147 days Dominant wind direction and frequency North, 19% Secondary wind direction and frequency South-east, 14% Average wind speed 1.0 (Dec) - 1.5 (Aug) m/s Source: Planning EIR and Project EIR

37. Air quality. In order to understand in detail the status-quo of air quality of the area’s environment where the project is located, this evaluation cited the monitoring data of Nanhu campus of Huangzhou District (about 15m of the nearest distance to the project) from the Environmental Impact Report of the Overall Planning of Nanhu Industrial Park in Huanggang City for analysis, and the monitoring time was from May 6th to May 12th, 2016. The monitoring results are presented in the following table.

38. According to the results in the above table, the average daily concentrations of NO2, SO2 and PM10 in the area where the project is located all meet the requirements of Class II standards under the Ambient Air Quality Standards (GB3095-2012). Both the monitoring results of ammonia and hydrogen sulfide can meet the maximum allowable concentration standard in the residential area under the Sanitary Standards for Industrial Enterprise Design (TJ36-79). Air quality of the environment where the project is located is sound.

39. Noise. In order to understand the status-quo of acoustic environment quality in the area where the project is located, the acoustic environment monitoring was carried out at representative sensitive points along the project site from August 15th to 16th, 2018, and a total of 19 noise monitoring points were set. The monitoring results are presented in Table C-3.

40. It can be seen from Table C-3 that, monitoring results at all points, except for Conglinwan 3, meet corresponding standard limit requirements for "Class 4a" area. Except for the road starting point, all other points meet the corresponding standard restrictions for "Class 2" area, with the maximum exceeding capacity of 1.6dB (A). The main reason for exceeding the standard is that it is affected by the surrounding road traffic noises.

41. Surface water quality. According to the Approval for the Applicable Standards on EIA of the ADB Financed Hubei Huanggang Urban Environment Improvement Project, prior to 2020, Class IV water quality standards under the Surface Water Environment Quality Standards is applied to the water bodies of Baitan Lake, Chiye Lake, Linglong Bay, Jinshui River, Dongtai River, Qingshui River, Canglang River, Dongchang River, and Chushui River. In order to understand the status quo of water quality of Baitan Lake, this time’s evaluation was conducted by using data from 2017 Annual Environmental Quality Status by Huanggang Environmental Protection Bureau released by Huanggang Environmental Protection Bureau.

Table C-4 Surface Water Quality of Baitan Lake

Cat. of Current Nutritional Indicators exceeding the Lake the Water status Standard function Quality level Worse Baitan Grade than Moderate TP, COD5, BOD Lake Ⅳ Grade V

42. According to the 2017 Annual Environmental Quality Status by Huanggang Environmental Protection Bureau, it’s known that each water quality indicator of Baitan Lake failed to meet the Class IV water quality requirements under the Surface Water Environment Quality Standards (GB3838-2002). The main reason is lack of complete sewage pipeline network in the surroundings, and some domestic sewage, for example, generated from the surrounding residents and schools has not yet been effectively treated.

43. In order to understand the status quo of water environmental quality of Chiye Lake, Chushui River, Qingshui river, Dongchang River and Dongtai River, Wuhan Zhongzhi Boce Detection Technology Co., Ltd. was commissioned to conduct the assessment, monitoring the current condition of Chiye Lake, Chushui River, Dongchang River and Dongtai River on August 17th, 2018. Specific water quality monitoring results are presented in Table C-5.

44. The above table shows that water quality of Chiye Lake, Chushui River, Dongchang River, Dongtai River, and Wuqi Channel failed to meet Class IV water quality requirements under the Surface Water Environment Quality Standards (GB3838-2002). Among them, the total phosphorus (TP) in Chiye Lake exceeds maximum the limit by 3.4 times and COD by 3.8 times. The TP of Chushui River’s water quality exceeds maximum the limit by 1.23 times, COD by 1.5 times, five-day COD by 0.03 times and NH3-N by 0.81 times. The TP in Dongchang River exceeds maximum the limit by 1.13 times, COD by 2.7 times and five-day COD by 0.13 times. The TP of Dongtai River’s water quality exceeds maximum the limit by 0.73 times, COD by 3.8 times and NH3-N by 0.31 times. The TP of Wuqi Channel’s water quality exceeds maximum the limit by 0.2 times and COD by 2.3 times. The main reasons for exceeding the standard are the lack of incomplete sewage pipeline network in the area, and some domestic sewage generated from surrounding residents and schools has not yet been effectively treated.

45. Sediment Quality. Dredging of Wuqi channel course is proposed under the project. In order to understand the current condition of sediment in the bed of Wuqi Channel, Wuhan Zhongzhi Boce Detection Technology Co., Ltd. was commissioned to monitor the current condition of sediment in the bed of Wuqi Channel on August 15th, 2018. One monitoring point was set up. The specific monitoring results are presented in Table C-6.

46. Based on the above-mentioned sediment monitoring results, it’s known that metal indicators of cadmium and nickel in the bed sediment of Wuqi channel cannot meet the requirements on limit standards under the Soil Environmental Quality Soil Risk Control Standards for Agricultural Land (Trail) (GB15618-2018), however, each indicator can meet the requirements on limit standards under the Soil Environmental Quality Soil Risk Control Standards for Construction Land (Trail) (GB36600-2018).

D. Anticipated Environmental Impacts and Mitigation

Measures

D1. Positive Environmental Impacts

47. This project will improve the environmental quality in the Baitan Lake planning area and the living conditions of present and future residents in the New East District (NED). NED development is a key thrust in the Huanggang Urban Master Plan (2011-2030) to provide infrastructure and public services that cannot now be provided in the old urban center due to space constraint, and is part of an overall plan to improve the effectiveness of Huangzhou District as the key urban center to drive socio-economic developments in Huanggang Municipality. This project therefore brings environmental, social and economic benefits to Huanggang Municipality and its residents.

48. Beneficiaries. The existing population of 12,000 and the future population of approximately 200,000 in the Baitan Lake planning area will directly benefit from this project. By 2030, the projected urban population of approximately 4.9 million in Huanggang Municipality will indirectly benefit from this project.

49. The cumulative impact of the engineering measures will improve the water quality of the two lakes from worse than Class V to Class IV for organic pollutants by 2020; nutrient levels will also be significantly reduced. Overall, the Project will provide healthy conditions and a pleasant environment for the residents in the Baitan Lake Basin.

D2. Summary of Environmental Impact Assessments during Construction Phase

50. Potential environmental impacts during construction includes the generation of dust and noise; wastewaters from the workforce; soil erosion due to excavation; loss of trees; and surface and groundwater contamination by oil and grease leaks from construction machines, pollution by the dredging and uncontrolled waste disposal. Epidemic diseases can be a concern due to the large number of mobile workers working on the construction site. These impacts are in general short-term in nature and can be minimized by proposed mitigation measures and good engineering and construction practices.

51. The proposed environmental mitigation measures for the new subprojects are summarized in Table D-1.

52. In order to effectively implement these mitigation measures, the Environmental Management Plan (EMP) was updated (see Appendix 1). The EMP has summarized all the mitigation measures and to be implemented by subproject construction contractors. The EMP also has listed responsibilities of all the parties who are involved in the subproject construction for supervision, enforcement and implementation of the mitigation measures. The EMP will be used as an integrated component of bidding documents and included in all the construction contracts for the new subprojects.

53. An environmental supervision mechanism will be established during the implementation of the new subprojects. A supervision group consisting of environmental supervision engineers (ESE) will be engaged by the subproject IAs to monitor the environmental performance of construction activities, including dust and noise control, construction wastes disposal, soil erosion control, tree replanting, worker safety, sanitation, and worker health. Implementation of the environmental management measures will be regularly reported to the IAs during the project implementation (normally on a monthly basis as part of monthly construction supervision reports) in order to keep track of environmental performance.

54. To reduce the risk of spreads of epidemic diseases, all construction workers will be provided with training and educational programs to increase the awareness and knowledge about the infection and prevention of epidemic diseases. Hygiene, sanitation and healthy lifestyle among the construction workers at the construction camps will be promoted and enhanced to minimize the opportunities of epidemic breakouts.

55. The environmental supervision mechanism mentioned above has been proved to be necessary and effective in several World Bank/ADB financed projects in China and other ongoing subprojects under the Project. With the implementation of the environmental supervision mechanism in the new subprojects, it is anticipated that the environmental impacts of the new subprojects during construction can be effectively controlled to the minimum and/or acceptable levels.

1. Air 56. The main pollutant is airborne dust. Airborne dust is mainly caused by such activities as excavation, blasting, demolition, vehicle movement and material handling. Since the project construction sites are relatively far away from residential areas, and the construction period is short in duration, adverse impacts resulting from the limited generation of airborne pollutants will be limited to the construction site 18 areas only. Potential airborne dust and emission from vehicles and construction machinery during material transportation are limited to the construction sites. Another pollutant is asphalt from the road construction.

57. The proposed mitigation measures in the Pollution Prevention Assessment Report are summarized below:

 Construction sites, transportation routes and materials handling sites will be water-sprayed on dry and windy days; especially if these sites are near sensitive receptors, such as residential areas.  Place the sand and stone storage place far away from the sensitive point of the environment, and cover with a tent cloth, regularly sprinkling water to suppress the dust.  An asphalt mixing station is not setup at a construction site, and the asphalt used is purchased from an existing asphalt mixing station.  Materials during transportation will be covered to avoid spillage.  Construction site entrance roads are equipped with vehicle washing facilities. 2. Noise 58. During the project construction period, noise sources are mainly from the operation of construction machineries during basic and road construction as well as transportation and vehicles.

59. Proposed mitigation measures for noise reduction in the Pollution Prevention Assessment Report are summarized below:

 Appropriate warning signs along main transportation routes will be established to limit the vehicle speed and prohibit honking.  Set up a fence in the course of construction when near the sensitive point.  Noisy machines will be properly maintained with necessary noise reduction technologies adopted, e.g., mobile sound barrier.  Nighttime use of high noisy machines, such as loader and grader, will be strictly prohibited within 282m from the residential area.  Transport vehicles should minimize driving at night, and are not allowed to horn when passing nearby the residential area with lowered speed in order to reduce the adverse impact of traffic noises on surrounding environment during the construction period. 3. Site Runoff and Wastewater 60. Site runoff from construction sites that are subject to excavation or earth works might lead to surface erosion and sediment loading. Sediment in runoff may be eventually carried to adjacent rivers near the project site through drainage channels.

61. With the implementation of site mitigation measures to control site runoff from working areas, and with the provision of sediment removal facilities, no adverse water quality impacts from site runoff are anticipated.

62. Wastewaters generated from construction activities may contain high SS concentrations. They may also contain a certain amount of grease and oil. Potential impacts due to such site wastewaters can be minimized if construction and site

19 management practices are implemented to ensure that litter, fuels, and solvents do not enter public drainage systems.

63. Domestic sewage generated from the workforce during construction is forbidden to directly discharge into public drainage systems or adjacent water bodies. Portable chemical toilets should be installed within construction sites. Wastewaters generated from kitchens should be discharged to public foul sewers or collected in a temporary storage tank. With a good control of domestic sewage, no adverse water quality impacts from the workforce sewage are anticipated to occur.

64. During drying process, a certain amount of residual water is generated at the sludge storage site. Pollutants discharged from residual water mainly exist in the form of fine particulars, which contains a certain amount of organics, nutrient salts, etc. Baffles are set up around the sludge storage site, and a sedimentation tank is set up at the outlet of the drainage ditch of the storage site. Mud waste water and residual silt water enter the special sedimentation tank through the drainage ditch and are reused after sedimentation. In addition, during construction in rainy days, the sludge storage site should be covered with necessary treatment, so as to reduce raining water scouring the storage site and to prevent sludge overflowing from the storage site, causing pollution to surrounding environment.

4. Solid Waste 65. Solid wastes are generated from construction (earthworks from excavation and the replaced pipeline) and workforce disposal. Proposed mitigation measures for solid waste management in the Pollution Prevention Assessment Report are summarized below:

 Garbage cans shall be placed at construction sites. Wastes collected shall be cleared and transported out regularly, and be handed over to environmental sanitation authority for proper treatment.  The project’s permanently disposed earthworks shall first apply for regional balance to the waste earth management office. With regard to the disposed earth that cannot be balanced, it shall be handled uniformly by the waste earth management authority. 5. Ecology 66. Land acquisition and construction activities, such as excavation and backfilling, and the dredging of the channel, can lead to damage to local vegetation and loss of biomass. However, timely restoration/compensation of soil and vegetation along the construction sites after the construction phase can minimize such ecological impacts. Dredging and cofferdam will cause a sharp increase in the concentration of suspended solids, which will affect the photosynthesis of phytoplankton and reduce the species and biomass of phytoplankton. Some laggards, burrows in the bottom and filter-feeding benthos will also be cleared out of the lake.

67. Proposed mitigation measures for the ecological protection are summarized below:

 Construction work shall be carried out strictly within construction area in order to avoid excessive damage to the surface vegetation;  Large-scale earthworks should avoid to be carried out during rainy seasons.  Upon completion of earthwork operation, measures shall be taken in a timely

20

manner to prevent water and soil erosion, such as road surface smoothing, tamping, brick and stone laying, and grass planting, etc.  Upon construction completion of main structure, measures such as grass planting, greening, etc. should be taken in a timely manner to restore the vegetation on exposed slope surface. Whether it’s side slope for earth filling or excavation, or excavation face for earth fetching, vegetation restoration is a more effective protective measure to prevent water and soil erosion.  When completed, suitable native aquatic plants can be planted according to the water environment to accelerate the restoration of the original ecological appearance and create conditions for the recovery of benthic communities and water purification.

D3. Summary of Environmental Impacts Assessments during Operational Phase

1. Noise 68. During the project operation period, no noise impact will be made from each component of the project.

2. Air Quality 69. Impact on the air quality of the external environment caused by the project mainly occurs during the project construction period, and Chiyehu Road under the project is a non-motorized lane, therefore, during the operational period, it will not have any impact on the external environment

3. Solid Waste 70. During the project operational period, no solid waste will be generated from each component of the project.

4. Ecology 71. Through dredging, sewage interception and water replenishment, sludge in the river bed that originally causes a high degree of pollution to the water body will be excavated out, concentration of each pollutant in the water will be significantly lowered, velocity of water flow will be accelerated, and the dissolved oxygen content in water will increase, all of which will lead to water quality improvement of the rivers, and be conducive to survival and reproduction of all kinds of aquatic and benthic organisms. Optimization of living environment will facilitate the growth and reproduction of aquatic organisms.

E. Findings and Conclusions

72. The construction project complies with the requirements of the local urban construction master plan and industrial policy. During the construction period, the project will produce a certain amount of wastewater, exhaust gas, noise and solid waste pollution, project design and this report put forward corresponding prevention measures and suggestions, as long as the environmental protection measures and the implementation of the principal part of the project achieve “three at the same time”, while strengthening the management of monitoring, the project's impact on the environment can be partially controlled and mitigated. Therefore, this evaluation considers that from the perspective of environmental protection, the implementation of the project is feasible at proposed locations according to the proposed content and scale.

73. Both positive and adverse environmental impacts of the new subprojects were identified and assessed. While largely beneficial to the natural and social environments in the subproject area, the subprojects are anticipated to cause some mild levels of adverse environmental and social impacts, including permanent occupation of land area and noise and disturbance caused by construction activities.

24

Nonetheless, these adverse impacts are mostly insignificant since the intensity of impact is limited and the size of impacted areas is small in scale.

74. At the construction stage, some environmental stressors, such as site runoff, sewage arising from the workforce, noise and dust, are not expected to cause significant adverse impacts to the nearby environment, provided that proper mitigation measures are implemented. During the operational phase, there will be no significant impact on the environment.

ATTACHMENT TO ENVIRONMENTAL IMPACT ASSESSMENT (EIA)

ENVIRONMENTAL MANAGEMENT PLAN (EMP)

For the proposed Hubei Huanggang Integrated Urban Environment Improvement Project, People’s Republic of China

Updated in September, 2018

Prepared by the Huanggang Municipal Government for the Asian Development Bank.

EMP-i

A. Introduction

1. This Environmental Management Plan (EMP) is developed for the Hubei Huanggang Integrated Urban Environment Improvement Project (the project) and defines all potential impacts of the project components and the mitigation and protection measures with the objective of avoiding or reducing these impacts to acceptable levels. The EMP also defines the institutional arrangements and mechanisms, the roles and responsibilities of different institutions, procedures and budgets for implementation of the EMP. The EMP seeks to ensure continuously improving environmental protection activities during preconstruction, construction, and operation in order to prevent, reduce, or mitigate adverse impacts and risks. The EMP draws on the findings of the project EIA, the domestic planning and project EIRs, the SEPP, PPTA and ADB review mission discussions and agreements with the relevant government agencies.

2. The EMP was updated for the changes proposed during the ADB mission in August 2016, and is updated again for the changes proposed for the mid-term adjustment in Septmeber 2018, and will be further updated if needed, at the end of the detailed design in order to be consistent with the final technical design. The final EMP, if updated, will be disclosed on the ADB project website and included in the Project Administration Manual (PAM). The EMP will also be included as a separate annex in all bidding and contract documents. The contractors will be made aware of their obligations to implement the EMP and to budget EMP implementation and monitoring costs in their proposals.

B. Institutional Responsibilities related to EMP implementation

3. As Executing Agency (EA), the Huanggang Municipal Government (HMG) will be responsible for the overall implementation and compliance with loan assurances and the EMP (including Environmental Monitoring Plan).

4. Huanggang Project Leading Group (HPLG). The HPLG has been established for the project comprising of senior officials from relevant government agencies, to facilitate inter-agency coordination, and to resolve any institutional problems affecting project implementation at municipal level.

5. The EA has established a Huanggang Project Management Office (HPMO), who will be responsible, on behalf of the EA, for the day-to-day management of the project. The HPMO will have the overall responsibility to supervise the implementation of environment mitigation measures, coordinate the project level Grievance Redress Mechanism (GRM) and report to ADB. By the time of project approval, the HPMO has been fully functional with 7 skilled staff at 5 units for (a) technical and engineering, (b) financial management, (c) land acquisition and resettlement coordination, (d) environmental management, (e) social and gender development, and (f) grievance redress. The HPMO has appointed one environment specialist to supervise the effective implementation of the EMP (under unit (d)) and to coordinate the project level GRM (under unit (f)).

6. HPMO has engaged the loan implementation consultants (LIC), Easen international Co., Ltd since June 2016. The ornithologist from the LIC team has undertaken water bird surveys in the Baitan Lake and Chiye Lake areas. The HPMO will prepare semi-annual environment monitoring reports and submit them to ADB.

EMP-1

7. HPMO also contracted an External Environment Monitor (EEM), NAREE Co., Ltd to conduct independent verification of EMP implementation and environmental impact monitoring results during the construction and operational stages of the project. A local environment monitoring company, Hubei Oukai Testing Services, Co., Ltd was also contracted by HPMO to conduct the environment impact monitoring during June 2016 to December 2016 in accordance with the environmental monitoring program described in Table EMP-41.HPMO then engaged Shenzhen Yuchi Testing Technology Co., Ltd. as the environment monitoring company for the next few years in July 2017.

8. Implementing Agency (IA). The Huanggang Urban Construction Investment Company Ltd. (HUCIC) is the IA for the project. It has hired the technical engineering design institutes (DI), implement project components, administer and monitor contractors and suppliers, and be responsible for construction supervision and quality control. To ensure that the contractors comply with the EMP provisions, HUCIC with the help and technical support of a Tendering Agent and the Loan Implementation Environmental Consultant (LIEC) under the LIC services, will prepare and provide the following specification clauses for incorporation into the bidding procedures: (i) a list of environmental management and monitoring requirements to be budgeted by the bidders in their proposals; (ii) environmental clauses for contractual terms and conditions; and (iii) major items in the EIA, and the full EMP. HUCIC has appointed on its staff one dedicated, trained, and qualified environment specialist to (i) supervise contractors and their compliance with the EMP; (ii) conduct regular site inspections; (iii) act as local entry point for the project GRM; (vi) submit environmental impact monitoring results provided by the EMS (contracted by the HPMO) to the HPMO and HEPB for verification and confirmation. HUCIC will hire licensed construction supervision companies (CSCs) to oversee construction works and compliance with contractor EMP, health and safety requirements.

9. Construction contractors will be responsible for implementing the mitigation measures during construction under the supervision of HUCIC (through the CSCs) and HPMO. In their bids, contractors will be required to respond to the environmental management and monitoring requirements defined in the EMP. Each contractor will be required to develop site specific EMPs and will assign a person responsible for environment, health and safety. After project completion, environmental management responsibilities will be handed over to O&M units.

10. Construction Supervision Companies (CSCs). CSCs will have the principal responsibility for overseeing contractor construction activities, and for ensuring that these activities are accomplished in compliance with the Project’s environment, health and safety requirements. The specific responsibilities of the CSCs will be to:

 Confirm that all plans, processes, approvals and requirements are in place to ensure EMP compliance prior to initiation of any work;

 Check the accomplishment of the environmental measures by Contractor crews against contractual obligations by: (a) evaluating contractor efforts and effectiveness; and (b) identifying circumstances requiring management decisions to evaluate variance or

1 The monitoring plan was revised in November 2016, and might be further revised as needed, in the framework of the EMP update after detailed design

EMP-2

compliance issues.

 Prepare monthly Standard Review Sheet (SRS) related to contractors' efforts and achievement for the purpose of monthly payment certificate for environmental activities.

 Identify circumstances requiring special study or activity, such as: (a) a committed activity linked to a specific construction activity; (b) special requirements related to a specific resource observations, i.e. archaeological control during excavation works; and (c) communicate to LIEC to allow timely and efficient implementation of specific commitments.

 Interface with Contractor's construction liaison personnel (advisory role only) to: (a) help communicate requirements; (b) obtain a hands-on view of special problems so that implementation difficulties can be communicated to LIEC to aid in problem resolution; (c) request consideration of work stoppage or a redirection of effort in the event that imminent potential for damage to a sensitive resource or a serious non-compliance situation is observed.

11. O&M Units. During the operational phase, HUCIC and the HEPB will periodically verify and monitor (through a licensed monitoring entity) the environmental management and implementation of mitigation measures by the operators (O&M Units) of the project components. The cost of mitigation measures in this phase will be borne by the relevant O&M Units, including:

 Huanggang Landscaping Bureau (HLB): for the operation and maintenance of the sub-surface flow and surface flow wetlands, and aquatic planting and land side landscaped areas;

 Huanggang Environmental Sanitation Bureau (HESB): for the operation, maintenance and management of solid waste collection and transfer, including the vessels, vehicles and the transfer station;

 Huanggang Aquatic Products Bureau (HAPB): for controlling and managing fish culture within Baitan Lake and Chiye Lake, and the stocking of fish and benthic fauna in these lakes;

 Huanggang Water Bureau (HWB): for operation and maintenance of flood control infrastructure such as embankments and the sluice gates.

12. Loan Implementation Environmental Consultant (LIEC). Under the loan implementation consultancy (LIC) services, a LIEC was engaged to support the project since June 2016. The LIEC was contracted by the HPMO, and will:

 assess the project components’ environmental readiness prior to implementation based on the readiness indicators defined in Table EMP-3 in the EMP;

 support HPMO in updating the EMP including monitoring plan as necessary to revise or incorporate additional environmental mitigation and monitoring measures, budget, institutional arrangements, etc., that may be required based on the detailed design; submit

EMP-3

to ADB for approval and disclosure; ensure compliance with the PRC’s environmental laws and regulations, ADB’s Safeguard Policy Statement (2009) and Public Communications Policy (2011);

C. Summary of Potential Impacts and Mitigation Measures

15. Potential environmental issues and impacts during the pre-construction, construction and operation phases, as identified in the EIA as well as corresponding mitigation measures designed to minimize the impacts are summarized in Table EMP-2. Mitigation or safeguard includes two types of environmental measures:

EMP-5

16. Those that will permanently become part of the infrastructure such as noise reduction materials and odor removal equipment for the solid waste transfer station. These will need to be included in the design of the facility by the design institutes, otherwise they won’t be built. The costs of building and maintaining these systems have already been included in the infrastructure construction and operating costs and therefore will not be double-counted as part of the EMP costs.

17. Those that are temporary measures particularly during the construction stage, such as dust suppression by watering and wheel washing, the use of quiet / low noise powered mechanical equipment, flocculants used to facilitate sedimentation of suspended solids in construction site runoff, etc. These will need to be included in the tender documents, otherwise they are not budgeted by the contractor and they won’t be done. The costs for implementing these measures are included in the EMP. The budgets for implementing these measures in this project add up to the amount of $2,152,000. This amount is made up of $1,111,000 for the implementation of soil erosion protection measures according to the SEPP (without double-counting the SEPP cost for vegetation/landscaping of permanent works areas, which have already been included in the civil works costs), and $1,041,000 for other mitigation measures.

18. The mitigation measures defined in the EMP has been checked and updated by the LIEC according to the changes proposed by HPMO and the domestic EIA prepared based on the changes. The mitigation measures were also incorporated into tender documents and the contracts for the civil works and was implemented by the contract which is under the construction. The mitigation measures will be further (i) checked and where necessary re-designed by the design institutes; (ii) incorporated into tender documents (where appropriate), construction contracts, and operational management plans; and (iii) implemented by contractors, HUCIC or HPMO, as relevant. The effectiveness of these measures will be evaluated based on the daily site supervisions by the CSCs, the results of the environmental monitoring conducted by the HEMS, and through EMP compliance verification conducted by the HPMO, the LIEC and the EEM.

D. Monitoring and Reporting 19. Monitoring will include project readiness monitoring (to be conducted by the HPMO with support of the LIEC), environmental impact monitoring (to be conducted by the External Environment Monitor (EEM); as well as by the contractors who will be required to conduct frequent noise and air quality monitoring around construction sites), and EMP compliance monitoring to verify EMP compliance during project implementation and project operation (to be conducted by HPMO and LIEC). Monitoring and reporting arrangements defined for this project are described below. 20. Assessment of project readiness. Before construction, the LIEC will assess the project’s readiness in terms of environmental management based on a set of indicators (Table EMP-3) and report it to ADB and the HPMO. This assessment will demonstrate that environmental commitments are being carried out and environmental management systems are in place before construction starts, or suggest corrective actions to ensure that all requirements are met.

21. Environmental Impact Monitoring. Table EMP-4 shows the environmental impact monitoring program specifically designed for this project, defining the requirements, including, scope, location, parameter, duration and frequency of monitoring during the construction and operational stages. Environmental impact monitoring will include monitoring of air quality, noise and water quality as described in Table EMP-4. Environmental monitoring during construction and operation will be conducted by the Huanggang environment monitoring station (HEMS) and a soil erosion monitoring entity, contracted by the contractors. Wildlife monitoring will be conducted by experienced

EMP-24

ornithologist(s). The EEM has been hired by HPMO to verify monitoring results. The monitoring program will be included in the project tendering documents, as well as the construction and operation contracts. 22. The environmental monitoring results will be compared with relevant PRC performance standards (Table EMP-5), and non-compliance with these standards will be highlighted in the monitoring reports. Monitoring results will be submitted by HEMS to HPMO and HUCIC quarterly, and will be reported in the semi-annual environmental monitoring reports by HPMO (with the support of the LIEC, see reporting plan in Table EMP-6).

23. EMP Monitoring. EMP monitoring will be undertaken by the HPMO, with support of the LIEC. HPMO will report to ADB the project’s adherence to the EMP, information on project implementation, environmental performance of the contractors, and environmental compliance through semi-annual environment progress reports (Table EMP-6). The LIEC will support the HPMO in developing the reports. The reports should confirm the project’s compliance with the EMP, local legislation such as PRC EIA requirements, and identify any environment related implementation issues and necessary corrective actions. The performance of the contractors in respect of environmental compliance will also be reported. The operation and performance of the project GRM, environmental institutional strengthening and training, and compliance with all covenants under the project will also be included in the report. 24. Environmental Acceptance Monitoring and Reporting. Within three months after each component completion, or no later than 1 year with permission of the HEPB, environmental acceptance monitoring and audit reports of each component completion shall be: (i) prepared by a licensed environmental monitoring institute in accordance with the PRC Management Method for Acceptance of Environmental Protection at Construction Project Completion (MEP, 2001), (ii) reviewed for approval of the official commencement of individual component operation by environmental authorities, and (iii) finally reported to ADB (Table EMP-6). The environmental acceptance reports of the component completions will indicate the timing, extent, effectiveness of completed mitigation and of maintenance,

1 The project applies PRC standards. A comparison of PRC standards with internationally accepted standards (as defined in the World Bank’s Environment Health and Safety Guidelines) was conducted and is described in Chapter II. The comparison confirmed that PRC standards are either internationally accepted, or have comparable standard limits with internationally accepted standards. A deviation from PRC practices and standards would make the task of compliance monitoring authorities unnecessarily complicated, and is deemed not justified.

E. Institutional Capacity Building and Training 25. The capacity of HPMO, HUCIC, O&M units such as HAPB, HESB and HWB, and contractors’ staff responsible for EMP implementation and supervision will be strengthened. All parties involved in implementing and supervising the EMP must have an understanding of the goals, methods, and practices of project environmental management. The project will address the lack of capacities and expertise in environmental management through (i) institutional capacity building, and (ii) training. 26. Institutional strengthening. The capacities of the HPMO and HUCIC to coordinate environmental management will be strengthened through a set of measures: i. The appointment of qualified environment specialists within the HPMO staff to be in charge of EMP coordination, including GRM and coordination of environmental impact monitoring, training, reporting, etc.; ii. The appointment of environmental specialists (international and national) under the loan implementation consultancy to guide HPMO and HUCIC in implementing the EMP and ensure compliance with ADB’s Safeguard Policy Statement (SPS 2009); iii. The appointment of environment specialist(s) by the HUCIC on its staff to conduct regular site inspections; and iv. The contracting of an external environment monitor to verify environment performance of the project.

EMP-28

27. Training. The HPMO, HUCIC, contractors and O&M units will receive training in EMP implementation, supervision, and reporting, and on the Grievance Redress Mechanism (Table EMP-7). Training will be facilitated by the LIEC with support of other experts under the loan implementation consultant services. The budget for training is estimated at $16,000.

28. Capacity building. In addition to training for EMP implementation, the project will provide a substantial capacity building package to ensure effective implementation of the project and sustainable O&M of the project facilities. The institutional components of the project will involve training by loan implementation consultants in operation and maintenance of completed facilities. Part of this training will focus on teaching staff how to use a set of indicators to monitor performance of the completed facilities. These indicators will be designed by loan implementation consultants prior to operation start-up. [A detailed capacity building program will be included after LFF.

F. Consultation, Participation and Information Disclosure 29. Consultation during project preparation. Chapter VII of the report has described the meaningful public participation and consultation implemented during project preparation. 30. Future public consultation plan. Plans for public involvement during construction and operation stages have been developed during project preparation. These plans include public participation in (i) monitoring impacts and mitigation measures during the construction and operation stages through informal interviews and disclosure of monitoring reports; and (ii) interviewing the public at project completion stage. These plans will include several types of public involvement, including site

EMP-29

visits, workshops, investigation of specific issues, interviews, and public hearings, as indicated in Table EMP-8. The budget for public consultation is estimated at approximately $10,000.

G. Grievance Redress Mechanism 31. Public participation, consultation and information disclosure undertaken as part of the local EIA process have discussed and addressed major community environmental concerns. Continued public participation and consultation has been emphasized as a key component of successful project implementation. As a result of this public participation and safeguard assessment during the initial stages of the project, major issues of grievance are not expected. However, unforeseen issues may occur. To settle such issues effectively, a Grievance Redress Mechanism (GRM) providing effective and transparent channels for lodging and addressing complaints and grievances has been defined. The GRM will be established prior to construction of the project components. The GRM is responsive to ADB’s Safeguard Policy Statement (2009) and PRC legislation. 32. The Proposed Project GRM. In consultation with the HPMO, HUCIC, HEPB and potentially affected people, the HPMO has established a complaints center and coordinate the GRM for the project for complaints related to both environmental and resettlement issues. The complaint center will direct all environmental complaints as appropriate to: (i) the contractors; (ii) HUCIC; (iii) O&M units. These are also entry points to whom the affected people could directly register their complaints. Complaints related to resettlement issues received by the complaints center will be directed to the relevant agencies in accordance with the resettlement GRM. Contact details for the complaints center and the entry points will be publicly disseminated on information boards at construction sites and nearby communities. Multiple means of using this mechanism, including face-to-face meetings, written complaints, telephone conversations, or e-mail, will be available. In the construction and the operational periods until ADB’s project completion report (PCR), the HPMO will report progress to the

EMP-30

ADB, and this will include reporting complaints and their resolution. 33. Basic steps for resolving complains are as follows and illustrated in Figure EMP-1: Step 1: For environmental problems during the construction stage, the affected person (AP) can register his/her complaint directly with the contractors, or through GRM access points (HPMO complaint center hotline, HUCIC, local EPB hotline). Contractors are required to set up a complaint hotline and designate a person in charge of handling complaints, and advertise the hotline number at the main entrance to each construction site, together with the hotline number of the HPMO complaint center. The contractors are required to maintain and update a Complaint Register to document all complaints. The contractors are also required to respond to the complainant in writing within 7 calendar days on their proposed solution and how it will be implemented. If the problem is resolved and the complainant is satisfied with the solution, the grievance handling ends here. The contractors are required to report complaints received, handled, resolved and unresolved to the HPMO complaint center immediately, and to HUCIC and HPMO monthly (through progress reporting). Step 2: If no appropriate solution can be found during step 1, the contractor has the obligation to forward the complaint to the HPMO complaint center. The AP may also decide to submit a written or oral complaint to the HPMO complaint center directly, by-passing step 1. A joint hotline for resettlement and environment issues will be established within the HPMO. For an oral complaint, proper written records will be made. Once a complaint is registered and put on file, the HPMO complaints center will immediately notify ADB. The HPMO complaint center will assess the eligibility of the complaint, identify the solution and provide a clear reply for the complainant within five (5) working days. Complaints related to land acquisition and resettlement issues will be directed to the relevant agencies in accordance with the resettlement GRM. The LIEC will assist the HPMO complaint center in addressing the complaint, and replying to the affected person. The HPMO complaint center will also inform the ADB project team and submit all relevant documents. Meanwhile, the HPMO complaint center will timely convey the complaint/grievance and suggested solution to the contractors, HUCIC and/or facility operator. The contractors during construction and the facility operator during operation will implement the agreed upon redress solution and report the outcome to the HPMO complaint center within fifteen (15) working days. Step 3: In case no solution can be identified by the HPMO complaint center, or the complainant is not satisfied with the proposed solution, the HPMO complaint center will organize, within two (2) weeks, a multi-stakeholder hearing (meeting) involving all relevant stakeholders (including the complainant, HUCIC, contractors, facility operator, local EPB, HPMO). The hearing shall identify a solution acceptable to all, and formulate an action plan.

34. The tracking and documenting of grievance resolutions by HPMO (through its complaints center) will include the following elements: (i) tracking forms and procedures for gathering information from project personnel and complainant(s), and notification procedure to ADB; (ii) dedicated staff to update the database routinely; (iii) a system to periodically evaluate the overall functioning of the mechanism; (iv) processes for informing stakeholders about the status of a case; and (v) procedures to retrieve data for reporting purposes, including the periodic reports to the ADB through the semi-annual environment progress reports. 35. The HPMO complaint center shall accept the complaints/grievances lodged by the AP free of charge. Any cost incurred should be covered by the contingency of the Project. The grievance procedures will remain valid throughout the duration of project construction and until project closure.

EMP-32

H. Cost Estimates 36. Cost estimates for EMP implementation, including mitigation measures, environmental impact monitoring, public consultation and training as presented in Tables EMP-2, EMP-4, EMP-7 and EMP-8 are summarized in Table EMP-9. Total budget for implementing these 4 items of the EMP is therefore $2,647,000. Excluded from the costs estimates are infrastructure costs which relate to environment and public health but which are already included in the project direct costs. Excluded are also capacity building packages, the remuneration costs for environment specialists who are staff members within HPMO and HUCIC, loan implementation consultants, and technical experts on equipment operation and maintenance, which are covered elsewhere in the project budget. Table EMP-9: Estimated Budget for Implementation of the Environmental Management Plan

EMP Item Estimated Cost External environmental monitoring (= environmental monitoring supervision) $49,000 Mitigation measures $2,152 ,000 Environmental impact monitoring $420,000 Training $16,000 Public consultation $10,000 Total $2,647,000

37. The HPMO will bear all environmental impact monitoring costs during the construction stage. O&M Units will bear the monitoring costs of the operational stage. HPMO will ensure the necessary budgets are available for the licensed environment monitoring entity (the external environment monitor) and the experienced ornithologist(s). Contractors will bear the costs for all mitigation measures during construction, including those specified in the tender and contract documents as well as those to mitigate unforeseen impacts due to their construction activities. The O&M units will bear the costs related to mitigation measures during operation. HUCIC and HPMO will bear the costs related to environmental supervision by their own staff. The project as a whole (through HPMO) will bear the costs for training, for coordinating the Grievance Redress Mechanism (GRM), and the Loan Implementation Environment Consultants under contract to HPMO.

I. Mechanisms for Feedback and Adjustment 38. The EMP were updated in December 2016 according to the changes proposed by the HPMO and will be further updated as needed by HPMO with assistance from the LIEC when there are design changes, changes in construction methods and program, poor environmental monitoring results, and if mitigation measures prove to be ineffective or inadequate. Based on environmental monitoring and reporting systems in place, HUCIC (with the support of the LIEC) shall assess whether further mitigation measures or improvement in environmental management practices are required as corrective actions. HPMO will inform ADB promptly on any changes to the project and needed adjustments to the EMP. The updated EMP will be submitted by HPMO to ADB for review and approval, and will be disclosed on the project website.
